Re: design of counters

ya u r right..but ur circuit size will decrease if u take 1 -14 as don't cares..

derive the code..using the truth table...15 next state= 16, 16 next state =17.. so on.
consider unused no.s as don't cares..


use some s/w to do this..it takes hell a lot of time to do manually..
